Krista Kafer’s column on oil and gas drilling regulations states that 500-foot setbacks from homes “shield homeowners from the noise, diesel fumes and sight of heavy machinery.”

Nothing could be further from the truth. Hundreds of truck trips carrying chemicals, water and sand are delivered to fracking sites. Very often, the smell of rotten eggs fills the air, with lighting 24/7. Citizens have to deal with the vibrations of the machinery 24/7.

To suggest that a lousy 500-foot setback shields the homeowners is not true, and quite frankly laughable.
